from above, is almost quadrangular and with the sides only slightly 

 convex, a little wider than long, and like the node strongly but not 

 closely punctured, more strongly so than the thorax. The 2nd 

 segment is more feebly punctured than the 1st, the rest only 

 indistinctly. The apical margins of the abdominal segments are 

 reddish. The claws are small and simple."

 £ . 12-13 mm. Black ; mandibles, flagellum, apex and base of 

 scape, the legs, and apex of abdomen dark castaneous red. A thin 

 golden pubescence all over ; a golden-brown pilosity on the node of 

 the petiole and on the abdomen. The sides of the head, thorax, node, 

 and 1st abdominal segment strongly and deeply punctured. The 

 punctures on the node and 1st segment are very large and rather 

 confluent, making the sculpturation almost rugose. The vertex of 

 the head somewhat finely punctured. Second abdominal segment with 

 shallower punctures than the 1st segment,* 3rd and 4th very finely 

 punctured, pygidium impunctate. The spaces between the punctures 

 on the first three segments striate, very finely so on the 3rd segment. 

 Sides of head slightly convex, rounded at the corners in front and 

 behind, hardly emarginate posteriorly. Clypeus feebly produced and 

 carinate in the middle, the carina obtuse at the apex. Frontal 

 carinae wide in front, smooth and moderately shining, as in granosa. 

 Mandibles triangular, shining and punctured. Byes nearer the 

 middle of the sides of the head than in granosa. The scape of the 

 antenna hardly reaches back as far as the occiput ; flagellum more 

 clavate than in granosa, 7th to 10th joints wider than long. Pro- 

 mesonotal suture distinct ; declivity of epinotum shining, and less 

 steep than in granosa. Node of petiole narrower in front than 

 behind, rounded in front and above, sub-trapezoid, posterior face 

 vertical and slightly concave. Ventral lamella angularly produced, 

 but not toothed. Otherwise similar to granosa. 



" $ . 9 - 5 mm. Testaceous yellow ; head brown; mesonotum and 

 scutellum brown with yellowish patches. The eyes occupy the 

 whole of the sides of the head. Ocelli large and placed on a raised 

 area. Wings pale yellowish, with nervures and stigma also pale. 

 Sub-opaque, very finely punctured and pubescent."

* Roger says, " As coarsely punctured as the 1st segment " ; the punctures are as 

 large, but certainly not so deep, when seen from above.
